For what it's worth, loading an intermediate document of some new type which
references other streams to be loaded adds a lot of complexity to the
browser implementation. It creates new states that the decoder can be in,
and introduces new failure modes. It creates new timing issues and possibly
new security issues.
"He was pierced for our transgressions, he was crushed for our iniquities;
the punishment that brought us peace was upon him, and by his wounds we are
healed. We all, like sheep, have gone astray, each of us has turned to his
own way; and the LORD has laid on him the iniquity of us all." [Isaiah
